观察并分析了磁力超声电镀对复合镀层的影响。通过对比分析上砂过程中加磁力和未加磁力、加厚过程中采用超声和未采用超声得到的复合镀层的微观结构，由于磁力的作用，金刚石磨料被均匀吸附在基体表面上，则镀层表面金刚石磨料分布均匀，特别在低电流区域内也能获得有效镀层，提高沉积效率、降低氢脆；采用超声波的机械振动作用，去除了附着在镀层上的氢气泡，这样可以提高镀层致密度，使镀层细致、紧密、孔隙少。

The influence of magnetic ultrasonic electroplating on the composite coating is observed and an-alyzed.Through comparison and analysis the microstructure of composite coating, which has been ob-tained at the process of sand with magnetic force and without magnetic force, upsetting with using ultra-sonic and without ultrasonic,due to the action of magnetic force, the abrasive of diamond is adsorbed uni-formly on the surface of the substrate.We could obtain the effective coating especially during the low cur-rent region, that improve the deposition efficiency and lower the hydrogen brittleness.By using ultrasonic mechanical vibration, which remove the hydrogen bubbles of attachment of the coating, improve the den-sity of the coating, also make the composite coating fine and close, less porosity.
